CLO'TH-OPERATED RESET FOR LIEASRING IVIACHINES.

Application led June 14, 1922. Serial No. 568,147.

To all whom t may conce/a.' s

Be it known that I, ANTHONY VANDER- vnLD, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Cloth-Operated Resets for Measuring Machines; and l do hereby declare the ollowing to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use'the same.

This invention relates to a novel construction of reset mechanism for use in measuring and computing machines ot' the type shown in my Patent No. LZOlQ. lny such machines, at the completion of an opera` tion, it is necessary to separate the measuring and presser rollers to remove the cloth measured, and at the same time apply ya brake to the mechanism so that it Vwill not run back to initial position in order that the amount measured and the price thereof may be read. It is also necessary that the mecha-nism be reset to initial starting Zero position before a succeeding operation is attempted in order to obviate the possibility that the succeeding operation shall show a larger amount than it should, or a total ot the two operations. To this end I have provided a novel reset mechanism which serves to insure that the brake shall be released and the resetting accomplished on the entrance of cloth into the machine if the reset has not been earlier accomplished. In other words, the cloth on its introduction into the machine automatically actuates the reset control mechanism, releasing the brake and freeing the mechanism for return to zero position. rlhe reset control mechanism also is capable of manual operation, and may be operated prior to the introduction of the cloth .into the machine so that the resetting shall have been accomplished before an operation is attempted. lvly present invention has tor .its primary object and purpose, the provision of relatively simple and practically operative mechanism tor the attainment of the above stated ends, together with provisions for the attainment of many other subsidiary ends, as will appear as understanding of the invention `is had from the following description ot the invention, taken in connection with the accompanying drawings, showing apreferred embodiment thereof, in which drawings, F ig. l is` a side elevation of the measuring and kcomputing machine of the invention.

Fig. 10 is a vtransverse vertical section through the measuring rolleron line 10*10, of Fig. 9.

Like reference characters refer to like parts in the severaltigures of the drawings.

In the construction of the machine,- a base l of substantially rectangular form is used on which the mechanism is supported This base and the mechanism above it is covered byy a suitable casing or housing having sides 2 and 3, a top 4, back l5 and front the latter terminating a distance above the base.' At the front lower portion of the inachine, a table Z positioned horizontally under the lower edges of the front 6 and adjacent sides 2 and 3, is-provided, `from which downwardly extending front and sides 8 are formed to meet/and connect to the base 1. irr'elatively deep slot 9 is made between the table 7 and the adjacent'loweredges of the casing for the entrance ofan edge portion of cloth,indicated at C, into the kmachine for measuring and computing price thereof. It

or housing whereby the cloth is readily entered and guided into the slot, this being one feature of novelty in the invention the importance ofl which will be more apparent when the automatic reset controlled by the cloth entrance is described. The major portion of the top el.` is cut away to provide an opening in which a piece of glass 10 is secured, and in like manner, a glass 11 is pro vided in connection With the front 6 of the casing.

The base 1 has an integral upwardly eX- tending post '1`2fformed therewith at one side fand extending transversely partly across the base, spaced from the end of which is an integral upwardly projecting web 13 (Fig. 7) and a shortdistance there- 'from a second web 14. A sleeve 15 extends through and is rotatably mounted'in post 12. A second sleeve 16 passes through and is rotatablymountedV in'sleeve 15 and at'its inner end has a mounting in the'web 13. A rod orshaft 17 passes through the second sleeve 16 and is'rotatably mounted therein, at its inner end' having a mounting .in Athe web 14'. An operating'lever 18 is attached to the o'utervend of the first sleeve 15, the same carrying a cutting blade 19 designed to cooperate with a second blade 2O secured tothe side 3 of the casing at the inner portion of the slot 9 for notching 4the cloth on depression of the lever.'

i the sides 2 and A second operating lever y21 is secured at the'outer end of sleeve l16 for turningfthe `same,`an'dat the inner end of the sleeve an arm 22 is fixed, extending upwardly and having a small roller 23 mounted at its upper endf A spring 24C (F 4t) is attached vatone end tothe arm 22 and attlie other end to a suitable stationary part ofthe machine, the tendency of which' .is to hold the arm 22 and the lever 21 in upper position.

A thirdoperating lever 25 is secured at the outer end of shaft 17 and adjacent vthe inner end between the webs 13 and 1d a cam 26 is tixedto act against lever 27 for operation of the frame 28 (Fig. 4e) on which the'presser roller 29 is mounted. as fully shown in iny'prior application for patent abovenoted. This presser roller is mounted under the table 7 and passes upwardly through a slot therein to against the measuring roller or the cloth C disposed between them when free to do so, Specifically, it forms no part of the present invention and need not be further outlined,

The mechanism carried by the basel is supported by va frame attached to and e-;- tending upwardly from the base, including a rear plate 30 paralleling the back 5 of the casing, a front plate 31, paralleling the front 6. and two side plates 32 and 33 paralleling A shaft 34s (Fig. li) is disposed horizontally between the plates 30 and 31, having a` bearing in the former and and pinions 38 for the actuation of shafts.

39 and 4:0 which are for the driving of the indicating mechanism of the measuring machine, not shown in the present case, as not concerned particularly with the invention.

ifi gear 41 (Fig. e) is Atired to shaft 39 and is in mesh with a pinion 42 fixed at one end of a roller 43 which, with a second parallel roller L14 (Fig. 7) is mounted horizontally between theends 45 of afraine, formed of said ends and two sides a6, and rest-ing on the upper edges of the sides 32 and 33 of the main supporting frame. rThe roller dit is hollow and has two ends 48 (Fig. 3) through which a rod 47 vpasses lengthwise of the roller, one end vbeing squared to lit a. like lopening in'one ofthe ends i5. A spring L19 is wound laround the rod and attached thereto at one end, the other end having connection to one of the ends 1&3, it being evident that the spring resists rotation of the roller in one direction andtenfds to turn it in the opposite direction after release from rolling or turning in the irstdirection. chart 5() carrying price indication characters is fixed at its` ends to the two rollers Li3 and #ist and winds from one to the other with the operation of the machine. A plate 51 with lon# gitudinal yopenings 52 therethrough lies above the chart, one vopening over each roller for the disclosure of the price characters through glass 10, asis common in machines of this type.

On the shaft 3e adjacent the pinion 37, a sheet metal U-shape'd member 53 (Fig.I 5) is mounted, one leg of the member being enlarged to make a bearing member 54 against which the brake may bear. 4This member is connected with the shaft by a springfshock absorbing device including a spring 55, but for the purposes of this invention it might as well be directly connected to the shaft. 1t rotates with the shaft and a kbralre placed against it stops yand checks rotation of said shaft 34.

A ro'd 5G (Figs. G and 9) is located be tween and supported at its ends in plates and A sheet metal brake bar 57 is pivotally mounted on the rod from which an integrally formed brake 5S depends to a point in front of the bearing member 54. it the one end. nearest Ythe plate 32, the bar 57 is formed with an integral `depending arm 59 for connection to the brake actuating mechanism as will later appear.

On the inner side of plate 32 in front lli lower end of the arm 59 heretofore de-` scribed, andan upwardly extending arm 65. A spring 66 is `attached at one end to the upper end of arm 65 and at its other end to the front plate 31, the tendency of the spring being to turn arm 65 forward and arm 63 upward and draw the brake 58 away from the bearing member 54.

A sheet metal lever 67 is pivotally mounted on the inner side of plate 32 near its upper end and in front of the member at 68, the major portion of the member extending downwardly below the pivot and at its lower end portion being'bent laterally and terminating in a finger 69 which passes through an elongated opening 7 0 in plate 32, the finger passing between plate 32 and the adjacent side2 of the housing to the slot at9 and then extending alongside the adjacent side-8 depending from the. table 7, as shown in Fig. 2. A pin 71 is connected with and proJects laterally from the upper end of member 67, to which one end of a coiled spring 72 is connected, the opposite end connecting to a pin 73 projecting from the member 60 a short distance above pivot61.

A third sheet metal member 74 is pivotally mounted at 75 to the member 60 near the upper end of the arm thereof. The member 74 extends to the rear a short distance y from its pivot and is then turned inwardly to make a stop lug or ear 76 to bear against the rear: edge of arm 65, beingl drawn thereagainst by spring 77 attached to the ear and said pinA 7 3. The member 74 extends a considerable distance farther in front of its pivot and at its frontend is formed with a camedge 78, against which pin 71 bears in one of its positions. Back of the front end a curved slot 79 is cut opening at the upper end and extendingdownwardly into the front portionY of member 74 between two pointed projections 80 and 81, as shown.

With this construction as described, the normal position of the parts when the mechanism is at initial Zero position is that shown in Figs. 5 and 8. The brake is off the member 54 and the mechanism may be rotated freely. The cloth drawn between the two rollers 29 and 36 drives the shaft 34 'and through the gearing shown,`the'l chart 50. At the end of the measuring operation, the

levers 18. 21 and 25 may all be depressed.`

the cloth being notched and the rollers separated. At the same time thebrake is set through `the following operation: Depressionvof the lever 21, vturns sleeve 16 and moves arm 22 forward to bring roller or wheel 23 against the rear 'edge of the lower arm 62 of member `60, there-by turning the member about its pivot. This causes a simultaneous downward movement of vthe arm 63 and a forcing of brake 58 against member 54. As soon as the lever 21 'has been depressed, it is released, whereupon the spring 24 carries the arm 22 to its initial position, as shown in Fig. 4. It will be notedthat the'link 64 and arm 63 make in effect a toggle lever and that the pivotal connection of the `same crosses the' dead center line ybetween the pivot 61 and the pivot connecting the link 64 to the part 59, whereupon the spring 66 serves to hold the brake against the part 54 when the parts are in the position shown in Fig. 4, but away when in the position shown in Fig. 5. The brake accordingly holds the mechanism from returning to starting position under the influence of spring 49 in roller 44. Vhen the necessary reading has been taken, the brake is to be released. This may be done in two ways. One by manually engaging the lower end of the finger 69 andinoving it backward, or the other by inserting the cloth in the. slot 9 fork the beginning of another operation, whereupon the cloth engages against the finger 69 and moves it backward. In Fig. 4, this is indicated, the cloth being about to engage against said finger 69.

No matter how the finger is engaged and operated, the lever 67 is turned about its pivot 68 with a consequent forward movement of the pin 71 which, located in the slot 79 serves to draw themember 74 forward and turn member 60 about its pivot, raising arm 68 and changing the position of the toggle lever which, as soon as the pivotal center passes the dead center line brings spring 66 into play to further swing member 60 about its pivot in the same direction. Or the parts take the position shown in Fig. 5. .Release of the brake places the mechanism under the influence of the spring 49 and the parts are rotated back to starting position. Accordingly, it is impossible to begin a measuring operation at the point where the last one left off, and when the returntoyzero position is started it is aparent to the operator that no attempted urther operation should `be begun until Zero position has kbeen reached. Of course, the operator may and generallywill operate the finger 69manually but if it is not done,

the cloth entrance will automatically take position until tllegcloth jis removed. is vindicate'd'in (t Ihebilakelias been set and t,all of the parts Voccupy the` same position as hin Fig. #teic'ept the leve-r .67 ivliicli has been',heldfbaclr` byv the'clothuC.
